s14 sr20 slight issues with idle and firing

[mat.roberts]

So simply put my sr seems to hunt a little bit at idle and has brutal fucking throttle response.also when idling it seems to have a miss every now and then nothing retarded making it sound like a tractor but def noticeable.every now and then as well it jerks around 2k-3k rpm and I hear backfires along with rich idle and poor gas milage.

Any idea what could cause this is a bone stock s14 sr running tomei 260 intake and exhaust cams on stock ecu with the cas and ignition timing set .


Thanks guys!

is your car tuned for those cams? and how did you set the timing?

First off, you're an idiot for putting cams in, not tuning it immediately, and expecting it to run like factory. Second, get your car tuned for those cams and I bet you'll see a huge difference.
